What does Binary search refer to?
Difficulty: Easy
About this MCQ
This Easy Algorithms question asks: What does Binary search refer to? The correct choice is A. A search algorithm that repeatedly divides a sorted array in half to locate a target value.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Algorithms items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Algorithms so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Algorithms item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A search algorithm that repeatedly divides a sorted array in half to locate a target value. ✓
- B. A graph traversal algorithm that explores as far as possible along each branch before backtracking.
Why not B: “A graph traversal algorithm that explores as far as possible along each branch before backtracking.” does not fit this question. The answer is A search algorithm that repeatedly divides a sorted array in half to locate a target value..
- C. A mathematical notation used to describe the upper bound of an algorithm's time or space complexity.
Why not C: “A mathematical notation used to describe the upper bound of an algorithm's time or space complexity.” does not fit this question. The answer is A search algorithm that repeatedly divides a sorted array in half to locate a target value..
- D. An algorithm that finds the shortest path between nodes in a graph with non-negative edge weights.
Why not D: “An algorithm that finds the shortest path between nodes in a graph with non-negative edge weights.” does not fit this question. The answer is A search algorithm that repeatedly divides a sorted array in half to locate a target value..
Correct answer
A. A search algorithm that repeatedly divides a sorted array in half to locate a target value.
